US Patent 9313943 Seed-double eliminator for a planting unit

A seed-double eliminator is described for a seeding machine that moves seed along a seed path. The seed-double eliminator may include a pocket with a pocket opening exposed to the seed path and a pocket cavity extending away from the seed path. A flexible extension may extend from within the pocket cavity toward the seed path. The flexible extension may be disposed to contact at least one seed of a seed-double pair being moved along the seed path by the seeding machine in order to remove the at least one seed from the seed path.
